[ft] BBox question

[Michele Petrazzo]

Another simple question (but I'm crazing... :) )
I load truetype font, a face, and a character. Set size. I want to know
its Bbox, so the width and height in pixel size.
(with another tool I see that Arial font with 50 dimension and 96
resolution, the size is 19 x 75)

For width, is simple: face->glyph->advanced.x / 64  = 19 (right)
And for height? I try to translate to pixel size all the face/glyph
dimension,( face->bbox, face->size->matrix, etc..) but I cannot find the
"75" value.
Can someone point me to the right direction?

Thanks,
Michele
